Main Circuit Terminal Functions - YASKAWA GA800 Series Installation & Primary Operation

7 Electrical Installation
*1 Set the wiring sequence to de-energize the drive with the fault relay output. If the drive outputs a fault during fault restart when you use
the fault restart function, set L5-02 = 1 [Fault Contact at Restart Select = Always Active] to de-energize the drive. Be careful when you
use a cut-off sequence. The default setting for L5-02 is 0 [Active Only when Not Restarting].
*2 When you install a DC link choke, you must remove the jumper between terminals +1 and +2.
*3 Models 2110 to 2415 and 4060 to 4720 have a DC link choke.
*4 When you use a regenerative converter, regenerative unit, or braking unit, set L8-55 = 0 [Internal DB TransistorProtection = Disable]. If
L8-55 = 1 [Protection Enabled], the drive will detect rF [Braking Resistor Fault].
*5 When you use a regenerative converter, regenerative unit, braking unit, braking resistor, or braking resistor unit, set L3-04 = 0 [Stall
Prevention during Decel = Disabled] If L3-04 = 1 [General Purpose], the drive could possibly not stop in the specified deceleration
time.
When you use an ERF-type braking resistor, set L8-01 = 1 [3% ERF DB Resistor Protection = Enabled] and set a wiring sequence to de-

energize the drive with the fault relay output.
*7 When you connect a braking unit (CDBR series) or a braking resistor unit (LKEB series) to drive models 2110, 2138, and 4103, make
sure that you use wires that are in the range of the applicable gauges for the drive. A junction terminal is necessary to connect wires that
are less than the applicable gauge to the drive. Contact Yaskawa or your nearest sales representative for more information about selection
and installation of the junction terminal.
*8 Cooling fan wiring is not necessary for self-cooling motors.
*9 Connect peripheral options to terminals -, +1, +2, B1, and B2.
WARNING Fire Hazard. Only connect factory-recommended devices or circuits to drive terminals B1, B2, -, +1, +2, and
+3 terminals. Do not connect AC power to these terminals. Incorrect wiring can cause damage to the drive and serious injury
or death from fire.
*10 Encoder circuit wiring (wiring to PG-B3 option card) is not necessary for applications that do not use motor speed feedback.
*11 Connect a 24 V power supply to terminals PS-AC to operate the control circuit while the main circuit power supply is OFF.
*12 Install the wire jumpers between terminals SC-SP and SC-SN to set the MFDI power supply (sinking/sourcing mode or internal/external
power supply).
NOTICE
Do not close the circuit between terminals SP-SN. A closed circuit between these terminals will cause
damage to the drive.
• Sinking Mode: Install a jumper between terminals SC and SP.
NOTICE
Damage to Equipment. Do not close the circuit between terminals SC-SN. If you close the circuits
terminals SC-SP and terminals SC-SN, it will cause damage to the drive.
• Sourcing Mode: Install a jumper between terminals SC and SN.
NOTICE Damage to Equipment. Do not close the circuit between terminals SC-SP. If you close the circuits
terminals SC-SP and terminals SC-SN, it will cause damage to the drive.
• External power supply: No jumper necessary between terminals SC-SN and terminals SC-SP.
*13 The maximum output current capacity for terminals +V and -V on the control circuit is 20 mA.
NOTICE Do not install a jumper between terminals +V, -V, and AC. A closed circuit between these terminals will
cause damage to the drive.
*14 DIP switches S1-1 to S1-3 set terminals A1 to A3 for voltage or current input. The default setting for S1-1 and S1-3 is voltage input ("V"
side). The default setting for S1-2 is current input ("I" side).
*15 DIP switch S4 sets terminal A3 for analog or PTC input. Set DIP switch S1-3 to the "V" side, and set H3-05 = 0 [Terminal A3 Signal
Level Select = 0 to 10V (Lower Limit at 0)] to set terminal A3 for PTC input with DIP switch S4.
*16 Do not ground the control circuit terminals AC or connect them to the drive.
WARNING Do not ground the AC control circuit terminals and only connect the AC terminals according to the product
instructions. If you connect the AC terminals incorrectly, it can cause damage to the drive.
*17 Connect the positive lead from an external 24 Vdc power supply to terminal PS and the negative lead to terminal AC.
NOTICE Connect terminals PS and AC correctly for the 24 V power supply. If you connect the wires to the incorrect
terminals, it will cause damage to the drive.
*18 Use multi-function analog monitor outputs with analog frequency meters, ammeters, voltmeters, and wattmeters. Do not use monitor
outputs with feedback-type signal devices.
*19 Jumper switch S5 sets terminal FM and AM for voltage or current output. The default setting for S5 is voltage output ("V" side).
*20 Set DIP switch S2 to "ON" to enable the termination resistor in the last drive in a MEMOBUS/Modbus network.
*21 Use only SOURCE Mode for Safe Disable input.
*22 Disconnect the jumpers between H1 and HC and H2 and HC to use the Safe Disable input.
